1Adaptability or versatility
If a multi-layer structure is adopted for phase modulation device, then the phase modulation capability is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent merges the functions of multiple traditional layers into a simplified double-layer configuration. The upper and lower patches together with the dielectric layer and conductive members integrate the phase modulation functionality that previously required more complex multi-layer structures, thereby reducing device complexity while maintaining phase modulation capability
Solution Approach 2:
The patent transitions from conventional planar single-layer or multi-layer structures to a three-dimensional double-layer configuration with vertical stacking. The upper and lower patches are positioned at different heights with conductive members providing vertical electrical connection, utilizing the third dimension (height) to achieve phase modulation with simpler overall structure
2Adaptability or versatility
If a multi-layer structure is adopted for phase modulation device, then the phase modulation capability is improved, but the manufacturing cost increases
Solution Approach 1:
The patent combines multiple functional layers into a streamlined double-layer structure, reducing the number of manufacturing steps, materials required, and assembly operations. The upper patch, lower patch, dielectric layer, and conductive members form an integrated structure that is easier and less costly to manufacture compared to traditional multi-layer devices
